I thought this might be a good idea to try to have a list of 1980s cartoon series that are now available in their entirety on DVD!
At this point, there's quite a few series that can be listed!
(This probably won't be in any particular order necessarily. For ease of convenience, I'm also listing a great Amazon.com list I found that has the links for these shows to order the DVDs! There are some other shows on the list too- but I am only listing the '80s shows here that have been released in their entirety. I'll also go ahead and list series that will be completed with upcoming releases.)

ThunderCats (4 Season volume sets are out with great extras too)
Danger Mouse (4 individual season sets or a complete series release is available)
Transformers (the original 1984 series- released by Rhino, but now out of print- though you can still find it on Amazon.com and Ebay)
(and Transformers: The Movie- the 1986 cartoon one, that is- is also on DVD)
He-Man and the Masters of the Universe (original 1983 series- out on DVD in 4 Season volume sets)
She-Ra, Princess of Power (3 Season volme sets wraps up this show)
(And yes- the He-Man and She-Ra Christmas Special is on DVD too)
The New Adventures of He-Man (2 volume sets complete this show)

The Super Mario Bros. Super Show! (2 volumes of this show have been released- unfortunately, it seems some episodes were left off due to rights issues.)
The Adventures of Super Mario Bros. 3 (the complete series in 1 set)
The Legend of Zelda (complete series set)
It's Punky Brewster (all but 1 episode of this series has been released on the "Punky Brewster" [live action show] DVD sets as bonuses- only missing "The Shoe Must Go On" episode)
The Adventures of the Little Prince (complete series set)
The Littles (complete series set)
Captain N: The Game Master (available in a "Complete Series" set- but you really need to also get "Captain N and the New Super Mario World" DVD set to get the third season.)

Robotech- (The Macross Saga, The Masters and New Generation are all available in complete sets)
Voltron: Defender of the Universe (original '80s series) (5 volume set wraps up this show)
Galaxy High School (2 individual volumes or 1 set packaged together available)
Blackstar (complete series set)
Dungeons & Dragons (complete series set)
Defenders of the Earth (2 volumes)
Adventures of the Galaxy Rangers (2 volumes)
Filmation's Ghostbusters (2 volumes)
Bravestarr (2 volumes)
(And the movie- "Bravestarr: The Legend" is out on DVD too)
New Adventures of The Lone Ranger/Zorro (2 volumes- lacks the Tarzan segments, due to rights issues dispute with the Buroughs family)
Rambo (complete series on 6 volumes)

Okay- I've mainly focused on Region 1 releases in the previous post, though I would imagine most if not all of those series are also available in Region 2 and other places, hopefully. Of course, if not- at least it's good to know that a region-free DVD player can play DVDs from any region.
Anyway, this list here is of '80s series released in their entirety on DVD but most all of these are in Region 2 (The UK) or some in Region 0 (which means they are region free and should work anywhere!). Hopefully, they will get a Region 1 (and all the other Regions) release eventually too.
(I've got links to purchase all these series below.)

The Mysterious Cities of Gold (complete series set)
Ulysses 31 (complete series set)
Around the World with Willy Fog (complete series set)
(Note- The follow-up series has been partially released with 3 volumes worth of Willy Fog in Journey to the Centre of the Earth, but I don't believe that one is available in its entirety just yet)
The Trap Door (complete series set)
Visionaries- Knights of the Magical Light (complete series set)
Pole Position (complete series set)
Dino Riders (complete series set)

Okay, that's all I can find for now. Some of these releases, like Visionaries, Pole Position, Dino Riders, Inhumanoids and M.A.S.K. are American cartoons that have (mostly) yet to get a Region 1 release, but they are available in their entirety in Region 2 on DVD. Others like The Mysterious Cities of Gold and Ulysses 31 are European, but have pretty big followings in North America and around the world from what I understand.
A lot of these I have only heard of and haven't seen myself, but I am familiar with SuperTed and Dogtanian and the Three Muskehounds and I can heartily recommend both! I grew up watching these shows (along with many others ) and enjoyed these very much. In fact, Dogtanian is one of the few anime shows I really like.
Anyway, for those with region-free DVD players, it's definitely worth checking into international releases- sometimes stuff gets released in one country that may not get released elsewhere.
Of course, hopefully eventually all these good quality cartoons from the 1980s will get the worldwide DVD releases they deserve!

And here's a few Marvel comics superhero releases to look forward to from Region 2!
(And of course, all of these I heartily recommend- especially Spider-Man and his Amazing Friends- an all time favorite as a child and now!)

Some more '80s goodness has been coming to DVD lately! We now have these 1980s cartoons that can be added to the list of those that are available on DVD in their entirety (some of these are scheduled to be released either later this year or in 2011, but I'm going to list the ones I know of anyway and I'll try to indicate the release dates as they're known.)

C.O.P.S.
(Mill Creek plans to release this show to DVD, including a re-release of episodes previously released by Shout! Factory, along with episodes that have as yet been unreleased- resulting in a complete series set most likely comprised of 2 volumes- with Volume 1 being planned for March 2011 (with the first 33 episodes) and Volume 2 planned for possibly as early as May 2011 (with the remaining 32 episodes.) Both sets would sell for about 10 bucks a piece.

This is available exclusively from Warner Archive's Manufacture-on-Demand department. They have been bringing a number of '80s (and other time periods) cartoon classics to DVD lately- so I would keep an eye out at their site too for further developments.
Both "Mr. T" and "Challenge of the Gobots" are on the way too- but so far, just the 1st. Season of "Mr. T" has been released and only the first mini-series for "Challenge of the Gobots" has been released- so we're still waiting for the entire series to come to DVD. But at least they are on their way! And I will more than likely post an update when we do see completion on these titles.

It's labelled as the Complete Series- but I should point out a technicality. This is ONLY the first 65 episodes. Unfortunately, the rights were not available for the 10 episode 2nd. Season, so that will not be included.
Perhaps rights for that can get negotiated and will come through later on down the road though...
